Redundant argument-based 'let' call

Reports a redundant argument-based let call.

let is redundant when the lambda parameter is only used as a qualifier in a call expression.

If you need to give a name to the qualifying expression, declare a local variable.

Example:

fun splitNumbers() {
    "1,2,3".let { it.split(',') }
}

The quick-fix removes the extra let() call:

fun example() {
    "1,2,3".split(',')
}

Alternative:

fun splitNumbers() {
    val numbers = "1,2,3"
    numbers.split(',')
}
